摘要
本文用Pseudoscatchard分析法测定了对照和烫伤后1、12,24小时大鼠肝胞液糖皮质激素特异结合部位结合参数的变化。与对照组相比,烫伤后1小时,糖皮质激素受体(GR)的结合容量显著减少,烫伤后12小时部分恢复,烫伤后24小时完全恢复。糖皮质激素低亲和力结合部位(LAGS)的结合容量在烫伤后12小时有下降趋势,但t检验与对照组相差不显著。GR和LAGS的解离常数在烫伤后无显著变化。对以上变化的可能病理和临床意义作了讨论。
The binding capacity (R_o) and apparant dissociation constant (K_d) of glucocrticoid binding sites in hepatic cytosol of normal and scalded rats were measured by pseudoscatchard analysis. Compared with control group, the levels of Ro of glucocorticoid receptor was significantly decreased 1 h after scalding, partialy recovered at 12h after scalding and fully recovered at 24 h after scalding. The levels of low-affinity glucocorticoid binding sites were also decreased 12 h after scalding, but had no statistical significance. The possible significance of these results has been discussed.
